The officer could issue a ticket based on the Mean Value Theorem if the ratio of the distance traveled (b-a)is greater than the speed limit. The MVT states that at some point between a and b, the slope of the graph(the speed of the car atan instant) must be equal to the slope of the secant line through the endpoints. In other words, there must besome cin the interval (a,b) such that f'(c)=f(b)-f(a)b-a.Click here to access the Explore Itin a new window.Select Scenario 1, which is about polynomials. Change the function tof(x)=1+2x2-2x3-1,3(a,f(a))=(,) and (b,f(b))=().(b) The slope of the secant line is. This means the secant line(c)To the nearest hundredth, the value ofc that satisfies the conclusion of the Mean Value Theorem in this case isc=(d)Atx=-1a,b
